<h1>Mesa 11.1.2 Release Notes / February 10, 2016</h1>

<p>
Mesa 11.1.2 is a bug fix release which fixes bugs found since the 11.1.1 release.
</p>
<p>
Mesa 11.1.2 implements the OpenGL 4.1 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 4.1.  OpenGL
4.1 is <strong>only</strong> available if requested at context creation
because compatibility contexts are not supported.
</p>
